I've just noticed you released -rt9, but I don't think my problem is listed as fixed.. I'll upgrade anyway, in a minute. The problem I'm having is that when the kernel probes my IDE devices it slows down, taking ages to complete the probe. Henceforth the kernel seems to work at a slower speed doing just about anything (compiling, etc.), but interactive performance is okay. It's a bizarre problem. Of course, I assumed this was due to the latest timer changes, and so I disabled CONFIG_HIGH_RES_TIMERS and went back to CONFIG_HPET_TIMER. This works perfectly. For the moment, is it worth debugging problems in the high res timers set or are there known (fixable) issues? -- Cheers, Alistair. 'No sense being pessimistic, it probably wouldn't work anyway.'
